Chemical Resistance Data

Only the highest quality raw materials available. These raw materials have outstanding resistance to both physical and chemical attack. The following chart should be used as a guide for evaluating the suitability of our products with the chemical agent to be used. Special consideration must be given to the expected service temperature, stress involved in the application and length and type of exposure (i.e. intermittent, or continuous). Contact our staff for information on chemicals not listed or when uncertain conditions exist.

* Stress-crack agent - Certain surface active materials, although they have no chemical effect on polyethylene, can accelerate the cracking of polyethylene when it is under stress. Although our tanks are generally stress-free, caution should be used when large tanks are unsupported, and welded fittings are used.

# Plasticizer - Certain types of chemicals are absorbed to varying degrees by polyethylene, causing swelling, weight gain, softening, and some loss of yield strength. These plasticizing materials cause no actual chemical degradation of the resin. Some of these chemicals have a strong plasticizing effect (e. g. aromatic hydrocarbons benzene), whereas others have weaker effects (e.g. gasoline). Certain plasticizers are sufficiently volatile that if they are removed from contact with the polyethylene, the part will "dry" out and return to it's original condition with no loss of properties.

+ Oxidizers - Oxidizers are the only group of materials capable of chemically degrading polyethylene. The effects on the polyethylene may be gradual even for strong oxidizers, and short term effects may not be measurable. However, if continuous, long-term exposure is intended, the chemical effects should be checked.
